Application filed April 20, 1907. Serial No. 369,371.

No. 881,542. Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CLARENCE L. BURG- NER, a citizen of the United States, residing at Clinton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Apparatus for Unloading Hay in Barns, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatus for unloading hay in barns, and the invention consists in the construction and combination of parts, substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a cross section of a barn showing my invention arranged therein and more or less diagrammatic. Fig. 2 is a cross section of a barn at right angles to Fig. 1 showing my invention therein and likewise more or less diagrammatic. Fig. 3 is an enlarged elevation of the carrier members of the invention and other parts considerably enlarged as compared with Figs. 1 and 2, and Fig. 4 is a view of the same mechanism at right angles to Fig. 3 and looking in from the right of Fig. 3. Fig. 5 is a side elevation, of the two carrier parts of the invention seen in Fig. 3 detached from each other, and Fig. 6 is an elevation of the same parts,

veyed thence to any desired portion of the mow by gravity, and there discharged. course, the original raising or lifting of the load by the foregoing mechanism is by power, as usual, such as horsepower attached to the rope or cable E.

rail A in the extreme top of the loft and comprises the hook member I), which has means for making temporar engagement with the body of the carrier after any of the well known connections now in use, and does not in itself constitute a novel portion of the present invention, excepting as the said hook member 6 is modified to adapt it to my present use. For example, when I have lifted the load from the wagon into the mow and am ready to distribute the same to a distant portion of the mow, my plan contemplates the moving of main carrier B to one side a distance sufficient to bring carrier 0 into 0 erative relation with the remainder of tF distributing mechanism, and when carrier 0 has reached such point, I plan to liberate the same from hook member I) and lodge said member C on carrying bar F. To this end, hook 2 of member I) is hinged or pivoted to the, stem or shank of member I) and behind said pivot point said hook has a notched extension 3 adapted to be engaged by a latch 4, so that when sheave or roller 5 of carrier 0 reaches a point directly above the fixed receiving bar F the said hook is automatically dropped and released from yoke 6 on carrier C, and said carrier C is then free to travel to its destination with its load, which presumably is sus ended from hook c.

Rail or ar F is supported upon a suitable rigid depending frame comprising upright G and the two braces g to ive it strength, and the said bar F is rigidly ed on said upright G so far as tilting thereon is concerned, but is adapted to rotate horizontally, and it becomes the initial rest of carrier C and its sheave 5 after being detached from carrier B. Such release is effected in this instance by a lateral rojection 7 fixed upon post or hanger G whic when the carrier parts are swung in towards said post, engages beneath latch 4 that locks hook 2 and raises saidlatch and liberates the hook, so that the hook drops and opens and carrier C is thereby released from carrier B. Yoke 6 on carrier is then drawn down by the weight of bell-crank lever 8, pivoted on carrier C and connected with said yo e by link 9, and the parts drop respeclikewise detached, but exhibiting different sides of said parts as will hereinafter more fully appear. Fig. 7 is an elevation of the distributing mechanism with a portion broken out at the center, whereby the hay is carried todifferent portions of the mow according as the mechanism is arranged to lodge the hay here or there in the mow. Fig. 8 is an elevation of the distributing carrier as will hereinafter more fully appear.

The idea of the invention as thus illustrated isto lift the hay from a wagon in a barn into the mow and then convey the hay from its point of elevation to one portion or to distribute the same mechanically instead of by hand, as will now appear. Thus, the invention comprises two carriers B and C, respectively, adapted to be mechanically united for lifting the hay into the mow and to be automatically separated for distributing purposes, whereby the distributing carrier is released from the lifting carrier and the-load is con- The lifting carrier B is adapted to run on tively into position as seen in Fig. 6, where the long portion of lever 8 serves the purpose of a side guard to confine carrier 0 upon its track, as will hereinafter appear. Now, having liberated carrier C from carrier B and delivered the same u on bar F, the said carrier 0 is ready to be f irt/i161 employed for conveying the load suspended therefrom, but not shown, to one part or another of the mow. To this end, I provide an arrangement for gravity conveyance of the load after it leaves the bar F, as seen in Fig. 7, and comprising bars F and H respectively and two ropes or cables J and L Each of these ropes is secured to one end of bar F and passed over sheaves 12 at the ends of bar H and thence over sheaves 13 near the middle of said bar and back and down over other sheaves 14 to drum or Windlass M, upon which said ropes are reversely wound, and are kept taut.

The sheaves 14 are supported on a cross head 15 apart from the cross member H by means of a rigid rod or bar 16, having a jointed connection with cross member H, Fig; 7 and ropes J-L pass thence to a sheave 17 hooked or otherwise engaged to the side of the hay-mow, while rope L passes over sheave 18 to Windlass M. Thus by means of said Windlass, which is operated by hand and shifting hook 17 to one portion or another about the side of the mow, the hay can be carried to one point or another in the mow as preferred, and after carrier 0 is moved off bar F to either rope J or L it will run by gravity to its destination. Bars or cross portions F and H are shown of the same length in this instance, and they may have more or less length so as to more or less compass the width of the mow, and if long enough no special shifting of hook 17 will be re uired.

ross-bar H is preferably formed in two parts, as bar F also may be, and sheaves 12 and 13 are supported between the sides of bar H and said ropes J and L are confined thereby, and carrier C has a hinged hook support 20 adapted to swing laterally in respect to said carrier body, and latch 22 pivoted at 23 is adapted to engage a lip 24 on said hook support 20 and lock it to said body Then as the carrier runs to the end of its travel on either rope J or L the latch 22 engages pin' 25 on bar H and is raised. When thus released the weight of the load tilts carrier C on the rope and lets it drop off with the hay hooks into the mow. Said carrier is then gathered up with the hooks and again restored to working position and so on.

If desired, rope E may be permitted to travel with auxiliary carrier 0 over the switch tracks and back again, keeping said carrier always under control of said rope E.

Briefly recapitulating the operation of the separate carriers, it will be understood first of all that carrier C is an auxiliary carrier for switching and carrying the load to either side of the central loft rail A, and to that end is also a detachable link member between carrier B and the hay forks which hold and support the load. I11 lifting the load at the start by rope or cable I both carrier C and hook b from which it is suspended, are raised until the hook part 1) comes to its place in or upon carrier B. The pull is now upon said carrier B and the same is caused to travel with the load over track A until sheave 5 of carrier C stands directly over bar F and upon which it is dropped when projection 7 unlatches hook 2 by lifting latch, 4-. Bar F is now rotated if the ropes J or L are so disposed in respect to the bar that running of the carrier thereover could not be otherwise accomplished and then the carrier is either pulled by rope off of the bar or pushed therefrom by a man in the loft until the said :arrier C is upon either one or the other of the inclined ropes J or L. From this point further travel is by gravity until said carrier O is released bodily from the rope by the weight of the load when latch 22 engages pin on bar ll. and permits said carrier to tilt to one side of the rope.

The cross bars F and II, well as various other parts of the apparatus are illustrated in Figs: 1 and 2 in a conventional or diagrammatic form as compared with the other ligures of the drawing.
